When I use DatabaseMetaData to load a particular table I get the following error:
Default Yes is an invalid expression since failed to parse Yes !

I get a similar error if I assume the database structure and attempt to insert into it.

This is with JDBC 3 - but I did not have this problem with the demo version. I need to use our licensed version as we are running more than 50 queries. Why do that behave differently with default values?
